Identification of highly conserved essential genes among virulent M. tuberculosis complex strains. (A) Strains used for comparative genomic analysis. (B) Results for pan-genome analysis by Roary. (C) Number of highly conserved genes among virulent M. tuberculosis complex. Core genes are conserved in >99% of strains, soft core genes are conserved in 95 to 99% of strains, shell genes are conserved in 15 to 95% of strains, and cloud genes are conserved in 0 to 15% of strains. (D) Numbers of genes that are essential for M. tuberculosis H37Rv survival in MtbYM rich medium and highly conserved among virulent M. tuberculosis complex strains.
